India’s forecasting tools that help in predicting the monsoon and the seasonal rains in India will soon get a high-tech makeover with India’s meteorology department spending close to Rs.400 crores on a new supercomputer that will help them predict the rain.

India, at present, uses statistical methods to predict the weather that was originally introduced in the 1920s under British colonial rule.


The new supercomputer is set to improve the accuracy of India’s prediction and would be ready in time to predict world’s weather forecast for next year’s rains.

The new supercomputer is based on a US model that has been tweaked for India.

The system would require immense computing power so as to generate three-dimensional models that will help predict how the monsoon is likely to develop.

According to experts, with this form of better forecasting, it would help India raise its farm output by nearly 15 per cent, as it will help farmers predict the best time to sow, irrigate or apply fertiliser to the crops and develop a rains fail plan in time for state-wide measures.

This, in turn, would be a major boon for a country which is already one of the world’s biggest producers and consumers of rice, wheat, sugar and cotton.


Talking about the new system, M. Rajeevan, a top scientist in the ministry of earth sciences, said :

“If everything goes well, by 2017 we’ll make this dynamical model operational by replacing the statistical model.”


In the past few years India has faced severe drought in the country, but according to latest prediction, 2016 monsoon would be the strongest since 1994.
